Why automate Embodied Carbon?

During the International Conference on Sustainability in Energy and Buildings, Ariyaratnea and Moncasterb (2014) analyzed how ineffective stand-alone embodied carbon calculation tools are, and how the solution can be found in the use of Building Information Modelling, to incorporate embodied carbon assessments in the general design process.

One Click LCA is based on exactly this principle, and allows you to automate the embodied carbon calculations, simply by importing your Revit, BIM, Excel, or gbXML file. Read more about the available integrations here.

Use your local data

One Click LCA’s Embodied Carbon in Construction Calculator has the most extensive LCA database of building materials from all over the world, including for example all BRE EPDs, IMPACT, INIES, Environdec and more).

Worried about the lack of an EPD database in your own country?  If your project is based in a country without a comprehensive local building LCA database, we have a local compensation methodology approved by BRE that allows to localize the data to get results that match the local manufacturing conditions for a specific area.


Working also with BREEAM, CEEQUAL, or DGNB?


Embodied Carbon in Construction Calculator has ready-made templates for any certification scheme and users can easily obtain standardized reports to submit to their green building certification scheme of choice. The software is officially approved and fully compliant with DGNB, LEED v4, BREEAM, and 20+ other certification schemes.

One Click LCA is also IMPACT-compliant and it has been rated by BRE as the highest performing LCA tool in history: it’s the only software able to deliver maximal LCA credits for any BREEAM project anywhere in the world, with a 100% Mat 01 rating.
